While some automatic navigation systems can use external measurements to determine their position (as the driver of a car uses road signs, or more recent automated systems use satellite data), others (such as those used in submarines) cannot. They must rely instead on internal measurements of the acceleration to determine their speed and position. Such inertial guidance systems have been in use since Word War II, and modern navigation would be impossible without them. This book describes the inertial technology used for guidance, control, and navigation, discussing in detail the principles, operation, and design of sensors, gyroscopes, and accelerometers, as well as the advantages and disadvantages of particular systems. An engineer with long practical experience in the field, the author elucidates the most recent developments in inertial guidance. Among these are fiber-optic gyroscopes, solid-state accelerometers, and the Global Positioning System. The book should be of interest to researchers and practicing engineers involved in systems engineering, aeronautics, space research, and navigation on land and on sea.This second edition has been brought up to date throughout, and includes new material on micromachined gyroscopes.

Mechanical Engineering, an engineering discipline borne of the needs of the in­ dustrial revolution, is once again asked to do its substantial share in the call for industrial renewal. The general call is urgent as we face profound issues of pro­ ductivity and competitiveness that require engineering solutions, among others. The Mechanical Engineering Series features graduate texts and research mono­ graphs intended to address the need for information in contemporary areas of me­ chanical engineering. The series is conceived as a comprehensive one that covers a broad range of concentrations important to mechanical engineering graduate education and re­ search. We are fortunate to have a distinguished roster of consulting editors on the advisory board, each an expert in one of the areas of concentration. The names of the consulting editors are listed on the next page of this volume. The areas of concentration are applied mechanics, biomechanics, computational mechanics, dynamic systems and control, energetics, mechanics of materials, processing, ther­ mal science, and tribology. I am pleased to present this volume in the Series: Modern Inertial Technology: Navigation, Guidance, and Control, Second Edition, by Anthony Lawrence. The selection of this volume underscores again the interest of the Mechanical Engi­ neering series to provide our readers with topical monographs as well as graduate texts in a wide variety of fields.

Anthony Lawrence is one of Australia'smost highly-regarded poets and winner of twoof the country's most prestigious poetry prizes.He characteristically sets his poems withinpowerful landscapes and seascapes. There is adramatic confrontation in them, between theelemental forces of nature, and those withinthe consciousness of his characters. His focusis on relationships, the rhythms of work, andthe presence of danger in these primal settings.In an interview, Lawrence says of his work:"I'd like to think that a couple of my poemsachieve this tricky balance: landscape veinedwith humanity, flora, fauna, what's imaginedand what's experienced ... I write about natureto define my life."Strategies for Confronting Fear, a selectionfrom six of his nine published collections ofpoetry plus a body of new work, is Lawrence'sfirst volume of poetry to be published in theUK."Lawrence's work is accessible while stillretaining the integrity of a unique poeticvision."Australian Book ReviewANTHONY LAWRENCE was born in 1957 and left school at 16, working first as a jackeroo and then travelling for several years before returning to New South Wales to become a teacher and writer. While working as a fisherman in Western Australia, he secured a literary fellowship whichenabled him to devote time to writing poetry. He has won numerous awards for his poetry, including a Senior Fellowship from the Australia Council, one of the most prestigious funding awards a writer can be accorded in Australia.
